How to Hide a Crack in a Windshieldby Mark O'Brien
Windshield cracks make your vehicle look bad and may cause glare that adversely affects your driving. You can hide a crack with a few simple supplies, but this is a temporary fix. It does not solve the structural problem, which eventually needs to be addressed.
Pour 1/4 cup of water to the mixing bowl. Then add a 1/2 teaspoon each of salt, bug repellent and rubbing alcohol. Stir the contents of the bowl until the salt is dissolved.
Dip the rag in the solution and rub it into the crack. Keep dipping the rag in the solution and rubbing it into the crack until all the solution is gone.
Allow the windshield to dry for several hours. The rubbing alcohol and bug spray chemically react together to soften the plastic cover originally manufactured over the glass windshield. The salt then acts as a temporary filler in the rubbing alcohol and bug spray mix.
